River Attack is a Shoot'em-up game in which you take on the role of an airplane pilot.
However, simply shooting around is not enough, as the pilot has to keep a constant eye on the fuel gauge during the continuous battle.
The pilot flies over a river through gorges guarded by enemy planes, balloons, helicopters, ships, jets and tanks. The aim is to penetrate as far as possible into enemy territory and to eliminate the enemy. If the pilot reaches or destroys a bridge, he reaches the next section.
